Despite scientists’ best efforts at communicating with the public, not everyone knows enough about the underlying science to make a call one way or the other. Not only is climate science very complex, but it has also been targeted by deliberate obfuscation campaigns.

If we lack the expertise to evaluate the detail behind a claim, we typically substitute judgment about something complex (like climate science) with judgment about something simple (the character of people who speak about climate science).

But there are ways to analyse the strength of an argument without needing specialist knowledge. My colleagues, Dave Kinkead from the University of Queensland Critical Thinking Project and John Cook from George Mason University in the US, and I published a paper yesterday in Environmental Research Letters on a critical thinking approach to climate change denial.

We applied this simple method to 42 common climate-contrarian arguments, and found that all of them contained errors in reasoning that are independent of the science itself.

In the video abstract for the paper, we outline an example of our approach, which can be described in six simple steps.

The authors discuss the myth that climate change is natural.

Six Steps to Evaluate Contrarian Climate Claims

Identify the claim: First, identify as simply as possible what the actual claim is. In this case, the argument is:

The climate is currently changing as a result of natural processes.
